Subject: [PATCH 06/10] ARM: add versatile family consolidated CLCD support
Date: Thu, 27 Jan 2011 12:59:51 +0000 [thread overview]
Message-ID: <E1PiRS3-0003mv-L3@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20110127125714.GD25968@n2100.arm.linux.org.uk>
This consolidates the CLCD panel definitions and memory allocation into
one location.
Rename the Sanyo 2.5in and Epson 2.2in displays after their respective
part numbers. Rather than using a general "Sanyo 2.5in" and "Epson
2.2in" description of the display panel, use the manufacturers part
number to be more specific. This helps people identify what the timings
actually refer to, which are panel specific.
While here, add CLCD capability information to each panel definition,
which has no effect until we add the board-level capabilities.
